How does an Art Market work and how can an artist become involved?

Hi guys. I’m trying to find some information on Art Markets for a presentation in my Art Institutions/Networks course in University. However, my group and I are having trouble finding some basic information on Art Markets. It’s a brief presentation that is just to provide ourselves and classmates some basic information about the Art World. Other groups have categories such as Art Education, Art Institutions etc. I’m easily coming across some art markets around the world, but am having trouble finding some general information to start with, and also information on how to become involved in the art market. My professor personally does not know much about this topic, so was not of much help. She only provided us with two links that didn’t really provide much general information. If anyone could help me out that would be great, whether you know off hand or know any good links that could help me with my research? Thank you. I really appreciate the help!
